Can you tell if a Ruby gem is really thread-safe or not? And how do you fix a seemingly thread-safety issue that can be something else entirely?We had no idea. So we asked Nate Berkopec to help us. Nate is an expert in Ruby performance.The verdict: nuking all shared global mutable state in your Ruby code is a bad idea if you don't know what you're doing!Listen to this episode to learn:- How and why faker-ruby became thread-unsafe, especially for Puma users- Questions to ask yourself when trying to debug thread-safety issues- Shared global mutable state is not always the villain, and is not the source of all thread-safety issues - Nate's "watch-out" list of things that can cause undesired behavior when running multi-threaded Ruby applications: Constants, Class Variables, and Rack Middleware.Episode Notes🔗 Full transcript and links-----A special thanks to Valentino Stoll, nfstern02, and Gregg P for sponsoring hexdevs!Enjoy!
